Here are three fixes that might help you resolve the Roomba error code 8:

Check the battery is installed

If you purchased the Roomba robot and received it recently, then it is possible that the battery is not installed in the robot, so remove the back panel and check if the battery is installed; if it is not in the robot, then install the genuine iRobot battery which must have come with the robot when you purchased it.

  • Check if the battery is properly fitted; if not, put corrugated paper either on the side or at the bottom to fit the battery perfectly. The battery should not move or shake in the compartment.
  • Reattach the bottom cover of the robot and then put it on charge.

Clean the Roomba battery terminals
